38 weeks- short femur, excess amniotic fluid

I had an ultrasound at my 38 week appointment because my midwife suspected baby was breech and she wanted to confirm. The ultrasound did confirm a breech position but also revealed a head measurement in the 97% and femur in the 4% as well as an amniotic fluid level slightly above normal. All ultrasounds up until this point had been perfect. I also had a cvs early on that was negative for genetic conditions (I have an older child with turners syndrome). I am being referred to maternal fetal medicine. Has anyone else experienced similar results (Short long bones or excess fluid) and what was your outcome?
